According to the website, Khloé is convinced the culprit is one of her assistants, a member of her house staff, a film crew member, an inspector or movers – someone who had knowledge of where she kept her valuables.

The Los Angeles Times earlier reported the theft was discovered Monday and police are investigating.

Law enforcement sources told the newspaper there were no signs of forced entry.

According to the Times, the 8,000-square-foot home went into escrow after it was listed last month for nearly $5.5 million.

Khloé and Lamar reportedly moved out of the residence after she filed for divorce in December.

She is not believed to suspect Lamar’s involvement in the theft as the basketball player is currently in Spain, according to TMZ.

Lamar was sentenced to three years probation after pleading no contest to driving under the influence stemming from an incident last year. He was also ordered to attend three months of alcohol abuse treatment, reports the Times.

The legal drama was only the latest in a string of tabloid headlines for Khloé and Lamar, who had also been accused of infidelity and drug abuse.

Last month, the 29-year-old reality star said dissolving her four-year marriage hasn’t stopped her from appreciating the good things in her life, however.

“Your life is meant for you to understand and process, not to make anyone else happy,” she told Cosmopolitan magazine

Khloé also expressed her profound love for her family, which includes matriarch Kris Jenner, stepfather Bruce Jenner, sisters Kendall and Kylie Jenner, as well as Kim, Kourtney and Rob Kardashian.

“[My family] makes me a better person,” she explained.

“We live in the public eye, so if one of us makes a mistake, it affects everyone… I have a such a great support system here. We’re so judged when we leave these walls that we try never to do that to one another.”
